TYPEWRITING MACHINE.

Application filed September 19, 1922. Serial No. 589,064.

To all whom, it may concern:

Be it known that I, ALFRED G. F. KUROW- SKI, a citizen of the United States, residing in Brooklyn Borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and more particularly to typewriting machines especially adapted for writing checks and making a copy on a continuous record-sheet of a part of the matter typed on each check of'a series of checks.

In writing checks it is customary to insert each check in the typewriter and type two lines upon it. The first line consists of the name of the payee and the numerals indicating the amount for 'which the check is drawn, and the second line consists of a statement of the amount for which the check is drawn spelled out in full. It is desirable to keep a condensed record of the checks by copying on a record-sheet the first typewritten line only of each check. With this end in view, there is provided, in addition to the usual ribbon mechanism for writing on the faces of the checks, an auxiliary ribbon mechanism adapted to be moved to and from position to cause the ribbon of the said mechanism to be effective to make a copy'on the record-sheet of the matter which is being typed on the face of a check. In the illustrated machine, the auxiliary ribbon is lowered into operative position as an incident of the movement of the feed-rollers into engagement with the platen, and is automaticallywithdrawn from operative position by the actuation of the line-spacing Means are provided for locking the a lever.

ribbon in its withdrawn position. IVhen a check is inserted in the machine, therefore, and the feed-rollers are moved into engagement with the platen, the first line written thereafter is copied, through the medium of the auxiliary ribbon, onto the record-sheet, but the second line is writtenon the check only, due to the fact that the auxiliary ribbon has been. withdrawn from operative po tion by as nemies tl l e p cin lever. Means are also provided whereby the ribbon may be moved to operative position, I

if desired, without actuating the feed-roll release lever. I

The auxiliary ribbon is carried by spools moun ed at the ends of the platen on a swinging frame, and this frame is mounted on a shaft extending from end to end of the carriage. The swinging movementsv im-- parted to the ribbon-carrying frame by movement of the line-spacing lever are uti lized to produce rotarymovements of the spools for feeding the ribbon. Feeding mechanism for this purpose is provided in conjunction with each spool, these mechanisms being'effective to feed the ribbon in opposite directions, and controlling means are provlded for rendering the ribbon-feedmg means for the different spools alternatively and selectively operative.

A paper-positioning and guiding frame i provided, having a plate for locating the check in proper position and an auxiliary roll which normally rests upon the platen to guide the record-sheet rearwardly out of the way of the auxiliaryribbon mechanism. a

This frame is adapted to be swung upwardly to, permit the insertion of the record-sheet between the platen and the auxiliary roll, and means are provided whereby upward swinging of the paper-guiding frame willbe I effectiveto'raise the auxiliary ribbon mech- I anism above the position to which it is moved by the line-spacing lever, in order to permit the insertion of therecord-sheet in;

the machine without obstruction.

Other features and advantages willhere- J inafter appear.

In the accompanying drawings, Figure 1 is a front elevation of a portion of a typewriting machine in which the improvements .of the present invention are embodied. I

Figure 2 is a plan view of the same. Figure 3 is a vertical sectional view of the carriage taken near the right end thereof, showingthe parts in their normal idle positions.

Figure 9 is a vertical section through the carriage, showing the paper-guiding frame swung upward to a position where further upward movement will be effective to raise the auxiliary ribbon mechanism.

Figure 10 is a vertical section illustrating the positions of the parts just after the actuation of'the line-spacing lever and before it has been returned to normal position.

Figure 11 is a vertical section of the earriage taken beyond the left end of the platen and looking toward the right. The lowered position of the auxiliary ribbon frame is illustrated in full lines and the elevated position is illustrated in brokenlines inthis view.

The typewriting machine of the present invention is provided with the usual ribbon 1, which is fed back and forth between spools 2 (only one of which is shown) and is threaded through a ribbon-guide3, to position it behind a type-guide in position to be struck by the types 5 for making an impression on the paper in the machine. A wire paper-guide 3 serves to assist .in'holding the paper toward the platen. A paper-sup; port- 7 may be mounted on the machine frame to assist in positioning checks inserted from the front of the machine. A platen-shaft 8, having a platen 9' thereon, is rotatably mounted in the platen-frame 10in thevusual manner. Paper-feed-rollers 11 are provided for eo-operating with the platen in feeding the paper, and these may be moved to operative and inoperative positions by the usual controlling means, which include a paper-release handle 12 fixed to a short shaft 13, which is mounted in the platen-frame, a crank-arn'i 1 1 on the shaft 13, and a link 15.

A rock-shaft 16, rotatably mounted in the ends of the platen-frame 10, has plates 17 fixed upon it near its opposite ends. The plates and rock-shaft form an auxiliary ribbon-carrying frame, each plate being provided with ribboirsupporting and guiding .mfliLIJ-S, as follows; Each of the plates l7 carries a bearing 18 in an upper part thereof, in which is mounted asleeve 19 formed integrally upon a ratchet-wheel 20. A shaft 21 is mounted in the sleeve 19. An angular plate spring 22 is connected to one end of the shaft'21 by a screw 23, and carries at its free end a finger 2 1-, which it presses into frictional engagement with the outside of the sleeve 19 through a hole 25 in the bearing 18 to re ulate the movemen s of the ratchetwheel 20. A ribbon-spool 26 is rotatably mountedon the shaft 21, being held in position thereon by a nut 27 received on a reduced threaded end 28- of the shaft. A pin 29 on the ratchet-wheel engages in a hole 30 in the ribbon-spool and compels the ratchet wheel and spool to rotate in, unison. The plates 17 extend forwardly to positions slightly in advance of thefront of the platen and are there bent substantially at right angles to direct them toward each other, whereby portions 31are provided extending transversely of the machine. The portions 31 extend inwardly to points slightly beyond the inner walls of the ribbon-spools 26, where they are bent forwardly to provide portions 32, which terminate in upwardlyextending arms 33. Pins 34 are mounted in the arms 33 and the main bodies of the plates 17, and have small spools 35. upon them for guiding the ribbon 36 without unnecessary friction. Inclined slots 37 in the portions 31 of the plates 17 and] vertical slots 38 in the portions '32 serve as guides for the ribbon-36. V

A spring 39, connectedto the platen-'lranie and to a pin 40 on the r'ocl -sl1aft 16, tends to swing the rock-shaft, and therefore the auxiliary ribbon-carrying frame, in a counter clockwise direction, as viewed in Figures 3 and 1. A cam 41, fixed upon the shaft 16, has a wall hl adapted to be engaged by a finger of a latch 4A, to prevent the movementof theauxiliary ribbon mechanism to lowered position whenever it is raised suit.- ciently to permit the finger of the latch to ride offthe high part-of the cam 41.. The latch 44': ispivoted. upon. pin 15 on the platenframe, and its finger 43 is urged toward the cam 41 by a coil spring'lti connected to the latch and to a pin 17 on the platen-frame. A hook 418, pivoted on the latch 14, is held by gravity inengagement with an angular portion 49 of the latch in a position to engage beneath a beak 50 on the link 15 of the feed-roller-controlling mechanism when. the link 15 is raised by movement of the paperreleasing handle 12 as anincident of the movement of the feed-rollers away from the platen (see Figure 4).' Movementof the handle 12' to restore the feed-rollers -to operative-positionwill be effective to draw the a hook 4-3 downward,-and'thereby to swing the latch fljl about its pivot. This will permit thesp-ring 3,9 to rotate the -,r,ocl csl 1af. 1G and thus move theauxiliary ribbon mechanism to lowered position. provided on the latch tt, whereby'the latch may be rocked to release the shaft 16 without actuation of the paper-releasing handle 12.

The usual line-spacing lever 52 is pivotally mounted at the left end of the carriage, and is effective to thrust rearwardly a slide 53. The slide 53 carries the usual pawl 54. for engaging the teeth of the ratchet-wheel 55 and moving them to effect line-spacing. The extent of the line-spacing movements is controlled as usual by a slide 56 having a latch 57 upon it for engaging a cam-surface 58 on the pawl 5 1. The slide 56 is movable to any one of three selected positions by a lever 59 pivoted on the carriage and connected to the slide through links 60 and 61. A plate 62, having slots 63 therein, is slidingly mounted on the top of the platen-frame. Screws 64 pass through the slots of the sliding plate 62, and are secured in the platen-frame for holding the plate 62 in position and guiding it in its sliding movements. The sliding plate 62 has a downwardly-bent and rearwardly-turned portion 65at its rear extremity, which is connected to the rear end of the slide 53 by a pin 66. A coil spring 67 is connected to the portion 65 of the sliding plate 62 and to a lug 68 on the platenframe, and is effective to move both the sliding plate 62 and the slots 63 forwardly when the linespacing lever 52 is released by the operator. A cam 69 is formed on the inner edge of the sliding plate 62 and has horizontal and inclined surfaces to engage a pin 70 on the out side of the plate 17 at the left end of the machine, the latter to raise the pin 70 when the plate 62 is moved rearwardly, to rock the plates 17 upwardly and rearwardly.

The auxiliary ribbon-spools and ratchetwheels, which are mounted on the plates 17, necessarily more rearwardly with the plates, and this rearward movement is utilized for effecting feeding of the ribbon. For this purpose, mechanisms are provided at opposite ends of the machine for co-operating with the ratchet-wheels 20, which are adapted to cause the ribbon to be fed in opposite directions. 7 Since these mechanisms are duplicates, one only will be described. A pawl 71. is rotatable on a stub-shaft 72 mounted in one end of the platen-frame, and its tooth 73 is urged toward the ratchetwheel 20b a coil spring 7a connected to the tail of the pawl and to the platen-frame. A pawl '75 is pivoted at 76 upon the plates 17 and has its tooth 77 urged toward the ratchet-wheel 20 by a coil spring 78 connected to an arm 79 of the pawland to the plates 17. An arm 80 onthe pawl 75 overlies the pawl 71, so that, when thepawl 71 is forcibly moved away from operative position, the pawl 7 5 will be awayfroni operative A finger-piece 51 isposition also. lVhen the ratchet-wheel is moved bodily with theplate 17, the tooth 73 ofthe pawl 71 engages a tooth of the r'atcheter'ed position, the pawl 75 will prevent retro- I grade movement of the ratchet-wheel, and the pawl 71 will slide along the ratchetwheel and engage av fresh tooth thereof.- A controlling lever 81, pivoted at 82 to the platen frame, has a forward end which overlies the pawl 71 and is adaptedto be depressed to move the pawl 71 away from the ratchet-wheel 20.

A shaft 83, mounted in brackets 84 on the platen-frame and having a handle 85, cari-ies angularlyrelated crank-arms 86 and 87 adjacent the respective levers 81 at the right and left ends of the platen 'frame. The lever 81 at the. left end of the platen-frame is provided with a notch 88 in its lower camsurface and a cam-surface 89 at the rear ther'eof, and the lever 81 at the right end of the platen-frame is provided with a notch 90 5 in its lower surface and a cam-surface 91 in advance thereof. The'crank-arms 86 and 87 carry rollers 92 and 93, respectively, for engaging the levers 81. When either of the rollers 92 or 93 1s iii-position to engage the notch in its lever 81, the tail of that'lever will be raised and its forward end depressed to move the ril')bon-feeding mechanism which it controls outof operative position. v The crank arms86 and'87 are so arranged on the shaft 83 that the movement of the' roller 93 into the notch 88 will move the roller 92 along the cam-surface 91, and thereby permit the feeding mechanism at the left end of the platen frame to become operative, and the movement of the roller 92 into the notch 90 will move the roller 93' f along the cam-surface 89, and thereby permit the feeding mechanlsm at the right end of the platen-frame to become operative.

Since these mechanisms feed the'ribbon in opposite directions, it will be seen that movement of the handle 85 from one to theother' 1 of the positions shown in Figure 8 will re- 11' verse the directionfof the ribbon feed. A paper-positioningframe 94' is mounted on the rock-shaft 16 for swinging movement with relation thereto. This frame carries an auxiliary paper-guiding roller 95 which guides the record-sheet rearward'ly and limits the downward swinging movement of the paper-positioningframe by engagement with the platen. A paper-guiding plate '96 is adjustably mounted onthe frontewall of the'frame 94 by screws 97 and nuts 98, which engage in horizontal slots 99 on the frame 9 i and in verticalslots 100' formed in ears 101 of the paper-guidingplate 96. The paperguiding plate has" papengaging flanges 102 \inter pused be we n th ha k of the heck and 1 and 103 formed along its upper and left edges, respectively. The frame 94 is pro vided with a finger-piece 104, by which it may be conveniently swung to a raised position to permit the insertion of the recordsheet in the machine. Pins 105 extend laterally inwardly from the ends of the frame 94 into positions to engage pins 106 on the shaft 16 when the frame 94 is raised and cause the shaft 16 to rotate in unison with the frame 94, thereby raising the auxiliary ribbon mechanism to the position shown in Figure 7. Detents 107, pivoted on short shafts 108 of the platen-frame are pressed by plate springs 109 into engagement with the rear surfaces of the frame 94, and are adapted to be received in rounded notches 110 of the frame to retain it yieldingly in the position of Figure 7.

The operation of the machine is as follows 1 The parts will normally be in the position, shown in Figure 3 with the auxiliary ribbon mechanism in lowered position. The operator lifts the finger-piece 104, raising the parts to the position of Figure 7, inserts therecord-sl'ieet, lowers the frame 94, and throws off the feed-rollers preparatory to the insertion of a check in-the machine. This brings the parts to the position shown in Figure 4. The handle 12 is then raised to move the feed-rollers intoengagement with the platen, and this restores the auxiliary ribbon mechanism to the position shown in Figure 3. The first line is typed on the check, and the auxiliary ribbon is then raised to the position of Figure 10 by actuation of the linespace lever, and is retained in that position by the latch 44. The second line is then typed, the feed-rollers are moved away from the platen, the written check is lifted out of the machine, and a new one is inserted. The feed-rollers are returned into engagement with the platen, and this movement ofv the feed-rollers is effective again to move the auxiliary ribbon in operative position for the writing'of the first line of the second check.

Should itbe desired to copy the second linewritten upon a check, or any other form used as the outside sheet, onto the record-sheet, the platen may be line-spaced throughthe knobs at its ends without raising the auxiliary ribbon mechanism, or the li1ie space lever may be operated and the ribbon: mechanism may then be lowered to the position of Figure 3 by depressing the linger-piece 51 of the latch 44. The auxiliary ribbon mechanism may also be raised without line-spacing, by lifting the frame 94 sufficiently to permitthe wall 42 on the cam 41 toengage behind the latch 44, and then returning the frame 94 to lowered position.

hen the auxiliary ribbon is in position to write upon the record-sheet, it will be prising a shaft and a the face of the record-sheet, and willtherefore make impressions not only on the face of the record-sheet but on the back of the check, as well. This fact is important be cause the writing on the back of the check serves to protect it against alteration. To alter the check it would be necessary to erase the written characters at the same point on the front and back of it. This would make a very thin place in the check which could be easily detected. The new characters could not be substituted on both the front and back of the check to resemble those erased except by the use of a special ma chine, such as that disclosed in this application. I
